Hi. I have had my Dalmatian for about 3 months now and she was pregnant when i got her, gave birth, and all fry died. I think she may be pregnant again but i cant find a gravid spot because of her coloring. I noticed her getting a little bossy with my male molly and pushing him away from my plecostomus' algae tablet. She definitely looks big but I'm not sure if she's pregnant or just fat. Please help
